Caution: Loads are guide values<br />
based on laboratory testing.<br />
On-site testing shall be performed<br />
for verifi cation of capacity since<br />
base material quality can vary<br />
widely.<br />
1. Tabulated loads are guide values based on<br />
laboratory testing. On-site testing shall be<br />
performed for verifi cation of capacity since<br />
base material quality can vary widely.<br />
2. Ultimate load is average load at failure of the<br />
base material. Heli-Tie fastener average<br />
ultimate steel strength is 3,885 pounds <strong>and</strong><br />
does not govern.<br />
3. Load at maximum permitted displacement is<br />
average load at displacement of 0.157 inches<br />
(4 mm). The designer shall apply a suitable<br />
factor of safety to these numbers to derive<br />
allowable service loads.<br />
4. Solid brick values for nominal 4-inch wide<br />
solid brick conforming to ASTM C62/C216,<br />
Grade SW. Type N mortar is prepared in<br />
accordance with UBC Section 2103.3 <strong>and</strong><br />
UBC St<strong>and</strong>ard 21-15, or IBC Section 2103.8.<br />
5. Hollow brick values for nominal 4-inch wide<br />
hollow brick conforming to ASTM C216/C652,<br />
Grade SW, Type HBS, Class H40V. Mortar is<br />
prepared in accordance with UBC Section<br />
2103.3 <strong>and</strong> UBC St<strong>and</strong>ard 21-15, or<br />
IBC Section 2103.8.<br />
6. Grout-fi lled CMU values for 8-inch wide<br />
lightweight, medium-weight <strong>and</strong> normal-weight<br />
concrete masonry units conforming to UBC<br />
St<strong>and</strong>ard 21-4 or ASTM C90, Grade N, Type ll.<br />
The masonry units must be fully grouted with<br />
grout conforming with UBC Section 2103.4 or<br />
IBC Section 2103.12. Type N mortar is<br />
prepared in accordance with UBC Section<br />
2103.3 <strong>and</strong> UBC St<strong>and</strong>ard 21-15, or<br />
IBC Section 2103.8.<br />
7. Hollow CMU values for 8-inch wide lightweight,<br />
medium-weight <strong>and</strong> normal-weight<br />
concrete masonry units conforming to UBC<br />
St<strong>and</strong>ard 21-4 or ASTM C90, Grade N, Type ll.<br />
Type N mortar is prepared in accordance with<br />
UBC Section 2103.3 <strong>and</strong> UBC St<strong>and</strong>ard 21-15,<br />
or IBC Section 2103.8.<br />
8. Normal-weight concrete values for concrete<br />
with minimum specifi ed <strong>com</strong>pressive strength<br />
of 2,500 psi.<br />
9. 2x4 wood stud values for nominal 2x4<br />
Spruce-Pine-Fir.<br />
10. Metal stud values for 20-gauge C-shape<br />
metal stud.<br />
11. For new construction. Anchor one end of tie<br />
into backup material. Embed other end into<br />
veneer mortar joint. Not for retrofi ts due to<br />
diffi culty of locating center of 2x4 or metal<br />
stud fl ange.<br />
